EeWrite E-Pad E-Ink Tablet Review

Browsing at 5 frames per second. It's got the features of a regular Android tablet, but it doesn't have the speed for a smooth experience. The EeWrite E-Pad is best as an e-reader with only the occasional light web browsing.

The EeWrite E-Pad is an ambitious tablet that dares to merge E-Ink technology with what is otherwise a standard 4G-enabled Android tablet. Swap out the IPS panel on a modern Android tablet for a high resolution E-Ink panel and you'll have a good idea on what the E-Pad is all about.

As of this writing, the E-Pad is in its Kickstarter phase which has already surpassed its initial crowdfunding goal. The pre-production unit we have here may not be an exact representation of the final model, but it's a close approximation nonetheless. The $400 to $500 E-Pad competes with other E-Ink-based Android devices including the Onyx Boox, Boyue Lifebook Mars, and the Barnes and Noble Nook.

Verdict

In review: EeWrite E-Pad tablet. Test model provided by EeWrite
In review: EeWrite E-Pad tablet. Test model provided by EeWrite

The EeWrite tablet is surprisingly light and easy to hold for long periods. It's over 100 g lighter than the iPad Pro 10.5 and it's thinner than most tablets at just 6.8 mm. Combine this with an attractive design and you have an E-Ink tablet that's well-suited for travel.

Unfortunately, that's where the major advantages of the EeWrite E-Pad end. Common Android features like 4G LTE, MicroSD reader, integrated speakers, Play Store access, Bluetooth, pen support, and WLAN are indubitably useful to have on an e-reader, but the E-Ink screen is abysmally slow to the point of frustration. While decent enough for reading e-books or manga, its response times are so poor that basic functions like navigation, touch-typing or writing, browsing, or scrolling all move unreliably and at a snail's pace. Video playback is impractical and the lack of a 3.5 mm audio jack means you'll need to rely on Bluetooth headphones for personal music playback. Perhaps an instant Search function would have made the experience a little faster.

The E-Pad is first and foremost an e-reader with secondary Android features. When those Android features are painfully slow and unresponsive, however, it's hard for us to recommend paying the high $400+ USD price premium. The E-Ink display just can't keep up with a modern Android OS and the mid-range MediaTek Helio X20 SoC is powerless to help it. But for e-books, comics, and music, the slow screen becomes more tolerable.
